Hi, I'm really new to the whole chicken thing and have a few questions. My hen is in her nesting box and not coming out this morning. Her body is placed totally different than when she's just laying an egg. Instead of her wings to her side, she has them spread out as if she's covering the eggs to warm them. If she's trying to hatch the eggs, can anyone tell me how long it takes to hatch an egg and how many hrs a day she needs to actually stay on the nest to incubate them? Thanks in advance for any information you can give me.
